AntoniaAllegra (or anyone who tried to upgrade to priority retroactively), when you did it, did the priority receipt say it was for settlement? And did you have to mail it in?
Thanks!
After purchasing through user pay services, the receipt actually had a paragraph about visitor visas, which is confusing.
"The Home Office will expedite the processing of your visa application and return of your documents. Customers may request this service if they are applying for a visitor visa (excluding student visas) and have traveled without difficulty in the last five years to one of the following countries: UK, USA, Australia, New Zealand, Canada or a Schengen country."
We sent a copy of the receipt to the same address we sent the original application to. My partner also dropped off a copy of the receipt in an addressed envelop to the Sheffield office.
